求解C++类中如何声明const void* GetX(){renturn &x};
怎样用const void*
#include <string>
class CData
{
private:
unsigned long int index;
public:
const void* GetDataIndex();
};
#include "CData.h"
const void* CData::GetDataIndex(){return &index;}
报错
class CData
{
private:
unsigned long int index;
public:
const void* GetDataIndex(){return &index;};
};
不报错......................
[解决办法]
报什么错？跟const void*应该没关系
[解决办法]
不要说又是分号，应该不是这种低级错误吧，。
